I've seen The Wizard of Oz, I've seen Return to Oz (Dorthy's journey back to Oz) and recently I had the absolute pleasure of seeing Wicked (the back story of how every one came to be) at Dallas Fair Park. Now I find this short movie "Heartless" (centers around the Tin Man) and I am very interested to watch it too. I read a great review ("simply outstanding storytelling") for it and the flick seems to be less than 25 minutes long. The music (I watched about five minutes of it) sounds pretty good too -- although nothing like Wicked.
If you watch it - let me know what ya think.
